It’s March 1985. More than a year has passed since Joe MacMillan (Lee Pace) set fire to a truck full of Cardiff Giant PCs, the last in a long string of destructive acts that burned the people that made the machine possible: Gordon Clark (Scoot McNairy), Donna Clark (Kerry Bishé), Cameron Howe (Mackenzie Davis) and John Bosworth (Toby Huss). The Giant is about to go the way of the dinosaur, like any number of personal computers to enter the market in the wake of IBM. The lesson is harsh but clear: in history, only the truly disruptive ideas are destined to matter.
